Abstract
The influence of moisture on organic S mineralization and the fate of both mineralization-derived and added sulfate were examined in A and B horizon soil samples from a hardwood forest. The sulfur-containing amino acid methionine was chosen to study organic S mineralization. At moisture contents over 30%, high levels of methionine mineralization were observed, and at lower moisture contents mineralization decreased substantially. For soil moistures lower than 10 and 20% for the A and B horizons, respectively, most of the added methionine remained nonmineralized following incubation. In addition to mineralization, a portion of the added methionine was also incorporated directly into organic matter. The highest levels of this incorporation were achieved at soil moistures between 20 and 35%. -from Authors
